How Long Can a 3D Printer Run? Fire Risk and What to Do About It!


3D printers are generally capable of running for a couple of days, ranging between 30 minutes to 7 days or even more.  There is a vast range of factors that may dictate the duration it takes to successfully 3D print a part. Some of these factors include the geometry and the overall size of the part to be printed, as well as the 3D printing technology deployed.

In case you are concerned that your 3D printer gives a sign of overheating, it is advisable not to leave it on overnight. You can perform this by triggering the pause command. Pausing your 3D printer should be an easy task since the feature is already inbuilt into the system.

The pause feature enables users to suspend the printing process and resume printing late on in the morning when your 3D printer has cooled. When you want to resume printing, simply use the resume print option available on the printer user interface window. Check out How Long Can You Pause a 3D Printer?

3D Printing Is Here To Stay

If you are planning to resume printing, there are a few possible issues you might think of, such as having the 3D print come out of position. To ensure minor adjustments such as adding nuts or changing the filament, you will be required to keep your bed and engine warm.

Is It Safe to Leave a 3D Printer Running Overnight?

At some point, you must have been caught in a situation where you start a 3D printing project that takes forever to complete. Therefore, before you engage in such a project, it is important to as yourself whether it will be safe to leave your 3D printer running unattended overnight.

It is not recommended that you leave your 3D printer running overnight unattended, since it poses major hazards. We have had reported cases of 3D printers catching fire as a result of heated bed failure or poor wiring. 3D prints may also detach from the surface when being printed, causing an extruding mess.

Do 3D Printers Require a Break?

3D printers need a break occasionally. However, it is manageable to run a long print process without a break if you maintain its parts properly. In case you have a 3D printer that is not only reliable but also prints multiple times without any hitches, then you shouldn’t worry about your 3D printer breaking down. Take your time to ensure that your printer has fresh belts and is well-lubricated.

3D printers are capable of running for hours, with some users claiming that they have used it up to 35 hours, resting state. Other 3D printers are also capable of running for more than 70 hours.  Some printers will run for longer hours without requiring a break compared to others.

Can You Pause a 3D Print and Turn It Off?

3D printing technology is amazing! You can use 3D printing technology to create art pieces, new products, and even prototypes. However, what if you need to pause the printing process? Yes, you can directly pause a 3D print from the 3D printer file instructions on your printer slicer, or via control software like Pronterface or OctoPrint.

However, it is not recommended to stop the printing process in progress, but you are allowed to pause a print. You can also, pause a 3D print process by simply selecting the ‘’Pause Print” option found on the printer display screen.

When you are set to resume your 3D printing, simply open the 3D printer user interface, and click on the “Resume” option. This command returns the 3D printer to its previous state. When you are not sure on the process of pausing a print on your 3D printer, do not worry since these instructions are always availed on the user interface

The pause option on the 3D printer user interface can be used to carry out the following functions:

  • Change colors of certain layers
  • Move the 3D printer to a different area
  • Replace filaments
  • Embed objects into your 3D printed object
  • Prevent turning on of heating elements

How Long Can You Pause a 3 D Printer?

You are allowed to pause a 3D printer as long as you may want, so long as you ensure the print does not move from the 3D printer bed.  Sometimes the 3D printer may be slow to reprint after changes or settings are made, hence it’s recommended that to just keep checking on it. The 3D print pausing duration may be as little as 5 minutes on the minimum count or as many hours as you choose. (Source)

If you leave your 3D printer idle for a long period of time, there are high chances that the print will drop off.

Can 3D Printers Catch Fire?

You may think that your 3D printer is the safest device in your house. However, 3D printer can prove to be one of the most dangerous devices you keep in the house. The filament inside your 3D printer used to create objects can become extremely hot, capable of catching fire if not stored properly.

In case you want to avoid the risk of your printer catching fire, ensure you store any unused filament far away from a heat source or an open flame. When printing anything using heated filament, always ensure that you have a fire extinguisher.

What is thermal runaway protection in 3d printers?

 In 3D printing technology, thermal runaway protection is basically a feature that detects when something sounds not right with the 3D printer heating. In Ender 3’s firmware, this program stops heating when the system detects that the target temperature is much higher than the actual temperature.
